SEARCH KEYWORD -- Tower of Hanoi

  Implementation of Tower of Hanoi

The Tower of Hanoi is a mathematical game or puzzle. It consists of three rods, and a number of disks of different sizes which can slide onto any rod. The puzzle starts with the disks in a neat stack in ascending order of size on one rod, the smallest at the top, thus making a conical shape. The objective of the puzzle is to move the entire stack to another rod, obeying the following rules: Only one disk may be moved at a time. Each move consists of taking the upper disk fro...

  Open Source Needs a New UI

As a freelance web developer, I’ve seen and used my fair share of open source web applications (and desktop software), and I’d like to point out something that I see all too often in open source projects: the user interface almost always lets the project down. Let me explain… The Problem I’ve used a considerable amount of open source software (web-based and desktop), and I feel that a large portion of them are let down by their UI. The functionality is brill...

  4 types of programmers

Not every one who writes code is a programmer. Programmers are people who live with programming. There are 4 types of programmers: scientist, coder, expert and artisan.Scientist, they are more like mathematicians rather than programmers. They invented various theories, algorithms and terminologies. Proofs and calculations in textbooks are all from these people. Moreover other programmers more or less benefit from their work. Sometimes one paper published by them can change the way of thinking of...

  PHP sucks (but, some frameworks don't)

I started web development with PHP, and I've decided I've had enough. Why? Keep reading.PHP (the language) sucks. There, I said it. 1029380128301928301823 GlobalsObject system hacked onC extension system sucksDocumentation sucks (read more; no, I'm not drunk)Has a terrible communityAll in all, designed by total idiots. You've probably heard this a ton of times before, but, here it is again. THERE ARE JUST WAY TOO MANY GLOBALS. Why in the world does md5() need to be global? Do you serio...

  Why Only Designers Can Create New Programming Languages

Attempts to verify the utility of languages stifle innovation. Christopher Mims 03/06/2012 30 Comments Compared to the versions that are hacked together late at night under insane deadline pressure, the programming languages to come out of academia are failures. Well, not all of them. History can speak for itself. Via UC Irvine computer scientist Cristina Videira Lopes, who deserves credit for any insight you might get from this post, which is a ...

  7 big mistakes that make your layout a disaster

Even though the web design field has become a real industry, building a website is part art, part science. The design of a website may attract people but it may also make them run away, it depends on the work of the web designer. The experience, the talent and the capacity of endeavor are the greatest tools of a web designer, a good layout is based on all of these and, besides that, it is a very time consuming activity.Making a good layout is difficult and judging its value is subjective, a desi...

  How Speeding The "Most Important Algorithm Of Our Lifetime" Could Change This Modern World

Math breakthroughs don't often capture the headlines--but MIT researchers have just made one that could lead to all sorts of amazing technological breakthroughs that in just a few years will touch every hour of your life. Last week at the Association for Computing Machinery's Symposium on Discrete Algorithms (SODA) a new way of calculating Fast Fourier Transforms was presented by a group of MIT researchers. It's possible that under cert...

  Obviously Correct

What do automatic memory management, static types and purity have in common? They are methods which take advantage of the fact that we can make programs obviously correct (for some partial definition of correctness) upon visual inspection. Code using automatic memory management is obviously correct for a class of memory bugs. Code using static types is obviously correct for a class of type bugs. Code using purity (no mutable references or side effects) isobviously c...

  Why learning Haskell/Python makes you a worse programmer

I've found, contrary to what you sometimes read, that learning Python and Haskell has not improved my programming using other languages. Haskell in particular, being so different from imperative languages, is supposed to give new insights into programming that will help you even when you are not using the language. My current experience doesn't exactly tally with this, and here is why:Demotivation.I find I think in Python, and even in Haskell to some extent, even though I have used Has...

  Cleansing data with Pig and storing JSON format to HBase with Pig UDF

Introduction This post will explain you the way to clean data and store JSON format to HBase. Hadoop architect experts also explain Apache Pig and its advantages in Hadoop in this post. Read more and find out how they do it. This post contains steps to do some basic clean the duplication data and convert the data to JSON format to store to HBase. Actually, we have some built-in lib to parse JSON in Pig but it is important to manipulate the JSON data in Java code before store to HBase. Apache Pig...
